I was just going to suggest mondo grass. Also liriope.
Those are mainstays in north Florida for fairly dense shade under live oaks,
etc. Pachysandra will also grow there, but it is slow to get started. If the
slope is not TOO steep, you could thickly mulch the area and plant a row of
boxwood, or low growing azaleas to define the area - and make it look
intentional instead of accidental.......
I don't think mondo grass or liriope is that hard to get started. If you
can get a good deal on them, you could plant individal sprigs about 1 foot
apart and cover a very large area that way. It would take them a year or so
to fill in, but the effect would be very neat and tidy after that. They are
pretty effective at keeping weeds, etc out. Clean out in the late fall would
be important - and I think some people mow theirs in the early spring to
stimulate nice new growth.
It's hard to sell a house when the yard looks like hell here. A nice
lawn makes the whole thing look neat and tidy and beautiful. A
haggard mess of a lawn is just depressing.

I'd be up for some ground cover that looked nice and prevented
erosion, but I have a hard time getting any landscaper to even call me
back.

I did have a bunch of mondo grass in front, but I ripped it out. That
would have been OK for the slope in front of my house.
